whats the deal with Cassandra?
From the token tool with 2 nodes and on the second cluster I get the below error.

The Apache Cassandra Project develops a highly scalable second-generation distributed database, bringing together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model. 3. Apache Cassandra WSO2 46 usages 4. Apache Cassandra 13 usages
If not set, the default directory is $CASSANDRA_HOME/data/hints. How often hints should be flushed from the internal buffers to disk. Will not trigger fsync. Min unit: ms Maximum size for a single hints file, in mebibytes. Min unit: MiB This option is commented out by default.
In case of RF = 1 a counter cache hit will cause Cassandra to skip the read before write entirely. With RF > 1 a counter cache hit will still help to reduce the duration of the lock hold, helping with hot counter cell updates, but will not allow skipping the read entirely.
Network authorization backend, implementing INetworkAuthorizer; used to restrict user access to certain DCs Out of the box, Cassandra provides org.apache.cassandra.auth. {AllowAllNetworkAuthorizer, CassandraNetworkAuthorizer}. AllowAllNetworkAuthorizer allows access to any DC to any user - set it to disable authorization.
These aren't valid Murmur3Partitioner tokens, they are RandomPartitioner tokens. Take a look at these DataStax docs on generating murmur3 tokens, or if you do want to use RandomPartitioner then edit your partitioner setting in cassandra.
Just for a clear comparison

You can generate murmur3 tokens using python (n is the number of nodes in the dc):
python -c 'print [str(((2**64 / n) * i) - 2**63) for i in range(n)]'
# eg for 4 nodes...
python -c 'print [str(((2**64 / 4) * i) - 2**63) for i in range(4)]'
